Abstract (en)
[origin: EP2568729A1] The present invention provides a method for Sounding Reference Signal (SRS) resource allocation in a Long Term Evolution (LTE) system, including: a system side setting different SRS transmission periods to correspond to different cycle shifts, and during the process of allocating SRS resources for user equipment (UE), setting a cycle shift adopted by the UE according to the SRS transmission period adopted by the UE. The method and apparatus of the present invention realize simple and effective SRS resource multiplexing with high utilization ratio among UEs with different periods.
